RESUMO
BACKGROUND: Genetic biomarkers are a promising and growing field in the management of bladder cancer in all stages. The aim of this paper is to understand the role of genetic urinary biomarkers in the follow up of patients with non muscle invasive bladder cancer where there is increasing evidence that they can play a role in avoiding invasive techniques. METHODS: Following PRISMA criteria, we have performed a systematic review. The search yielded 164 unique articles, of which 21 articles were included involving a total of 7261 patients. Sixteen of the articles were DNA based biomarkers, analyzing different methylations, microsatellite aberrations and gene mutations. Five articles studied the role of RNA based biomarkers, based on measuring levels of different combinations of mRNA. QUADAS2 critical evaluation of each paper has been reported. RESULTS: There are not randomized control trials comparing any biomarker with the gold standard follow-up, and the level of evidence is 2B in almost all the studies. Negative predictive value varies between 55 and 98.5%, being superior in RNA based biomarkers. CONCLUSIONS: Although cystoscopy and cytology are the gold standard for non muscle invasive bladder cancer surveillance, genetic urinary biomarkers are a promising tool to avoid invasive explorations to the patients with a safe profile of similar sensitivity and negative predictive value. The accuracy that genetic biomarkers can offer should be taken into account to modify the paradigm of surveillance in non muscle invasive bladder cancer patients, especially in high-risk ones where many invasive explorations are recommended and biomarkers experiment better results.

AIM: There are two classical managements in gastroschisis: primary or delayed closure. From 2007 on, a multidisciplinary approach protocol based in preterm caesarean delivery at 34-35th gestational age (in order to minimize peel injury) plus primary closure is followed in our institution. Prior to this, term delivery, either by caesarean section or not, was the rule. METHODS: Retrospective study of gastroschisis's patients before (1978-2006) and after (2007-2016) protocol approval. Complex gastroschisis frequency, peel's presence, primary or delayed closure, complications, re-interventions, neonatal intensive care unit (NICU) length of stay, age at onset of enteral nutrition, total parenteral nutrition's length and length of stay were compared. MAIN RESULTS: Study groups: before (12 patients) and after (13 newborns) the protocol implantation (pre/post). Nine complex gastroschisis were observed in the pre-protocol period, compared to one in the post-protocol era (p= 0.001). The re-interventions also decreased: 58.33% in the pre-protocol vs. 15.38% in the post-protocol group (p= 0.025). Complications rate were 66.67% before protocol vs. 23.07% after protocol (p= 0.028). NICU length of stay decreased from 40 ± 32 to 17 ± 12 days (p= 0.025). Parenteral total nutrition length was 61 ± 36 in the pre-protocol vs. 15 ± 6 in the port-protocol eras, respectively (p= 0.043). The age at onset of enteral nutrition was 34 ± 26 vs. 9 ± 5 days (p= 0.004) and hospitalization length was 98 ± 81 days pre vs. 35 ± 15 days post protocol implantation (p= 0.011). CONCLUSIONS: The protocol implantation has allowed primary closure, decreased hospitalization; reduced complications and mortality rate as well.
OBJETIVOS: Clásicamente existen dos manejos de las gastrosquisis: cierre directo o diferido. Nosotros apostamos por el cierre directo aplicando un protocolo de actuación en el que se programa cesárea a las 34-35 semanas de gestación para minimizar el "peel". MATERIAL Y METODO: Estudio retrospectivo de los pacientes con gastrosquisis en los períodos pre (1978-2006) y post (2007-2016) implantación del protocolo, comparando frecuencia de gastrosquisis complejas, la presencia o ausencia de peel, cierre directo o diferido, complicaciones, reintervenciones, días de ingreso en unidad de cuidados intensivos, edad al inicio de nutrición enteral, nutrición parenteral total y días de hospitalización. RESULTADOS: Grupo de estudio: previo (12) y posterior (13) al protocolo (previo/post). La frecuencia de gastrosquisis complejas en el período previo fue de 9 neonatos, en el período post solo 1 (p= 0,001). El número de reintervenciones fue de 58,33% previo vs. 15,38% post (p= 0,025). Las complicaciones postoperatorias fueron 66,67% previo frente a 23,07% post (p= 0,028) y existió una disminución de los días de estancia en la unidad de cuidados intensivos de 40 ± 32 vs. 17 ± 12 (p= 0,025) y de los días de nutrición parenteral (61 ± 36 frente a 15 ± 6; p= 0,043). La edad al inicio de la nutrición enteral fue de 34 ± 26 vs. 9 ± 5 días (p= 0,004) y los días de hospitalización fueron de 98 ± 81 días previo frente a 35 ± 15 días post protocolo (p= 0,011). CONCLUSIONES: La implantación del protocolo ha permitido el cierre directo, la disminución de la estancia hospitalaria, de las complicaciones y de la mortalidad.

INTRODUCTION: Neonatal surgical wound infection occurs in almost 50% of neonatal procedures. It increases the rates of morbimortality in neonatal units. There is no guidelines about prevention of wound infection in neonatal surgery. We present our results after changing our behaviour in neonatal surgery. MATERIALS AND METHODS: Comparative study between 2 groups. In order to decrease wound infection at the end of the procedure gloves, covertures and surgical instruments were changed and saline and antiseptic solutions were used during laparotomy closing. Group P included procedures with these recommendations and Group NP without them. Age, weight, surgery, infection, length of stay, and mortality were analized between groups through a logistic regression model. RESULTS: Group P included 55 procedures in 32 patients, median weight 1,300 g (1,000-2,100), 19 median days of life (6-40), 5 postoperative wound problems (9%). Group NP included 26 procedures in 14 neonates, median weight 1,700 g (700-2,500), 20 median days of life (3-33), 14 wound problems (53.8%). We decrease the wound problems in our patients in 44.8% (p < 0.0001). Additionally, the protection provided by our recommendations was maintained after adjustment by weight, age and type of pathology (0.07) p= 0.000. CONCLUSIONS: Simple changes in during the procedures in neonatal surgery can reduce the appearance of wound infection and morbidity.
OBJETIVOS: La infección de herida quirúrgica neonatal tiene una incidencia de hasta el 50% y produce un aumento de morbimortalidad. No existen recomendaciones preventivas consensuadas en la literatura. Presentamos los resultados tras la implantación de un protocolo creado en nuestro Servicio para cierre de laparotomía en cirugía neonatal contaminada y sucia. MATERIAL Y METODOS: Estudio ambispectivo de las laparotomías neonatales realizadas durante 32 meses comparando los resultados con un grupo de pacientes intervenidos durante un período previo similar. El protocolo incluye cambio de guantes, de campo y material quirúrgico, lavado por planos con antiséptico y sutura antibacteriana en el cierre. Se analizan edad, peso, tipo de intervención, infección, estancia hospitalaria y mortalidad y se compara con un grupo similar de pacientes intervenidos de forma previa a la creación del protocolo (NP) y se analiza la influencia del protocolo en la aparición de infección mediante regresión logística. RESULTADOS: El grupo P incluye 55 laparotomías en 32 neonatos con mediana de peso 1.300 g (1.000-2.100), mediana de edad 19 días (6-40) con 3 infecciones de herida (2 cultivos positivos) y 2 dehiscencias leves (9%). El grupo NP incluyó 26 intervenciones en 14 neonatos, mediana de peso 1.700 g (700-2.500), mediana de edad 20 días (3-33), 14 infecciones (53,8%), 8 cultivos positivos y 2 muertes. Se redujo un 44,8% la aparición de infección (p < 0,0001) y el efecto protector del protocolo se mantuvo después del ajuste por peso, edad y tipo de patología (0,07) p= 0,000. CONCLUSIONES: La sencilla modificación de la asepsia y técnica de cierre ha contribuido a disminuir considerablemente la tasa de infección y morbimortalidad en nuestros pacientes y consideramos que es necesario hacer conciencia de ello.

BACKGROUND: Management of high-grade T1 (HGT1) bladder cancer represents a major challenge. We studied a treatment strategy according to substaging by depth of lamina propria invasion. METHODS: In this prospective observational cohort study, patients received initial transurethral resection (TUR), mitomycin-C, and BCG. Subjects with shallower lamina propria invasion (HGT1a) were followed without further surgery, whereas subjects with HGT1b received a second TUR. Association of clinical and histological features with outcomes (primary: progression; secondary: recurrence and cancer-specific survival) was assessed using Cox regression. RESULTS: Median age was 71 years; 89.5% were males, with 89 (44.5%) cases T1a and 111 (55.5%) T1b. At median follow-up of 71 months, disease progression was observed in 31 (15.5%) and in univariate analysis, substaging, carcinoma in situ, tumour size, and tumour pattern predicted progression. On multivariate analysis only substaging, associated carcinoma in situ, and tumour size remained significant for progression. CONCLUSIONS: In HGT1 bladder cancer, the strategy of performing a second TUR only in T1b cases results in a global low progression rate of 15.5%. Tumours deeply invading the lamina propria (HGT1b) showed a three-fold increase in risk of progression. Substaging should be routinely evaluated, with HGT1b cases being thoroughly evaluated for cystectomy. Inclusion in the TNM system should also be carefully considered.

OBJECTIVES: Surgical site infection (SSI) has a considerable impact on neonatal morbidity. There are known risk factors such type of surgery (clean/contaminated), prematurity, surgical length, hypoalbuminemia, previous infection, prolonged mechanical ventilation, and so on. Many perioperative factors have not been studied, opposite to adults. We have developed a survey on intraoperative attitudes and measures, as surgical wound management in Neonates among pediatric surgeons, to seek for a wider consense. METHODS: Multi-response survey with 22 items, based on the Surgical Infection Society NIH 2008 clinical guideline. Each item poses a question on perioperative attitudes, surgical aspects and wound management. Each question is subdivided in two categories, depending on urgency and type of surgery (clean/contaminated). RESULTS: 159 surveys were sent. Among those, we received back 51 (32%). 69% of the interviewed surgeons use clorhexidin to prepare surgical field, 25% use Iodine solutions. 69% never use diathermy to incise skin. There was no agreement on the use of sterile plastic adhesive drapes, intra-cavity lavage, changing surgical gloves/material, or wound irrigation during closure. 82% never use cyanocrilate dressing. Intracuticular skin suture and simple stitches were used indistinctly. Wound management and dressings were not uniform and depended on each pediatric unit. CONCLUSIONS: The survey reflects the lack of consensus regarding prophylactic measures and wound management among pediatric surgeons who care after surgical neonates.
OBJETIVOS: La infección de herida quirúrgica (IHQ) es una causa frecuente de morbimortalidad en Neonatología. Existen factores de riesgo conocidos: tipo de cirugía (sucia/contaminada/limpia), prematuridad, duración de intervención, hipoalbuminemia, infección previa, ventilación mecánica prolongada y contaminación de vía central. Otros factores perioperatorios no han sido estudiados en neonatos, sí en adultos. Desarrollamos una encuesta sobre las actitudes y las medidas, intraoperatorias y de manejo de herida. Pretendemos dilucidar si existe consenso sobre la profilaxis de IHQ neonatal. METODOS: Encuesta con 22 ítems, basada en la guía de prevención de la IHQ en adultos (Surgical Infection Society, 2008). Cada ítem cuestiona temas sobre hábitos perioperatorios, intra y postoperatorios, relacionados con el manejo de la herida quirúrgica en el neonato, y consta de dos preguntas, según sea cirugía sucia/urgente o limpia/contaminada. Las opciones de respuesta son 4: siempre, con frecuencia, raramente y nunca. Enviamos la encuesta a cirujanos pediátricos españoles mediante correo electrónico en el primer trimestre del 2012. RESULTADOS: Se enviaron 159 encuestas. 51 (32%) respondieron. 69% emplean clorhexidina para preparar campo, 25% usan povidona iodada. Solo el 51% refirió dejar actuar siempre un minuto el antiséptico. 69% nunca usan bisturí eléctrico en piel para ampliar herida. No hubo respuestas unánimes en cuanto al uso de paños adhesivos protectores del campo, la irrigación de planos con suero o antisépticos durante el cierre, el empleo de drenajes, cambio de guantes y/o material al iniciar el cierre (cirugía sucia). El 72% y el 82% nunca emplean cianocrilato como cierre o apósito en neonatos, respectivamente. En cirugía sucia, 43% suturan piel con intradérmica y 49% con puntos sueltos. CONCLUSIONES: La distribución de respuestas refleja la falta de consenso sobre los aspectos de la técnica quirúrgica y el manejo perioperatorio que podrían estar relacionados con la profilaxis de IHQ neonatal.
RESUMO
INTRODUCTION: Gallstone removal preserving the gallbladder is a therapeutic option in cholelithiasis. Our group has made use of this technique for twenty-five years in pediatric patients. The purpose of this review was to study gallstone recurrence and gallbladder motility. MATERIALS AND METHODS: Patients who had gallstones removed with this technique from 1989 until 2013 were contacted and asked about digestive or other health problems. A sonographic assessment was made in order to look for gallstone recurrence and to measure gallbladder volumes and contraction after fasting and after consuming a fatty meal. RESULTS: All patients are asymptomatic except a girl who suffered colic pain and who had a gallstone recurrence. The median of volume after fasting was 18.37 cc and after consuming the meal 7.16 cc. The median of gallbladder contraction was 57.63%. CONCLUSIONS: A gallstone relapse was identified (10%). Long-term follow up showed an excellent gallbladder function and contraction (greater than 30%) without other recurrences. Based on our experience, in patients properly selected cholecistolithotomy is an interesting option in children.

INTRODUCTION: The most frequent long term side effects of Hirschsprung's disease (HD) surgery are obstructive problems and fecal incontinence. In this study, we analyse long term functional results of the two most used surgical techniques (Duhamel-D- and De la Torre-dlT-) from the patient's point of view, through quality of life and functionality questionnaires. METHODS: We selected short segment HD patients ≥ 4 years) that were operated in our unit from 1996 until 2011. We employed two validated questionnaires: Bowel Function Score (BFS) and Gastrointestinal Quality of Life Index (GIQLI). Both questionnaires were also tested in two control age matched groups, each for every arm (controlD or control dlT). RESULTS: Among 28 preselected patients, 22 (78.6%) answered both questionnaires. Group D (10 patients) showed more constipation: 60% vs. 16.7% ( p = 0.01). Patients in group dlT (12 patients) showed more leaks: 58.3 vs. 10% (p = 0.03). Results of both questionnaires were higher (better) in Group D: 16 vs. 12.8 points (BFS, p = 0.007) and 74.1 vs. 69.8 (GIQLI, p = 0.17). The control group showed an overall better scores than HD patients: 17.2 vs. 14.3 (BFS p = 0.001) and 75.9 vs. 71.8 (GIQLI, p = 0.04). Separately, both groups of patients showed worse scores when compared with each control group. DISCUSSION: Our results are similar to other studies, where global scores of functional results and quality of life are worse in operated HD patients than in age matched controls. Fecal incontinence has more impact on social scores than constipation. Due to the fact that our dlT patients have more frequently fecal leaks, their scores are worse than in the D group. Nevertheless, patients in dlT group are younger and may improve their results as they get older, as it is often the case in operated HD patients.

INTRODUCTION AND OBJECTIVE: Robotic-assisted laparoscopic prostatectomy (PLAR) seems to improve functional outcomes, however there is not a consensus of a standard procedure. The aim of this study was to identify the PLAR "state of art" in Catalonia, Spain. MATERIAL AND METHODS: This was a cross-sectional survey-based study conducted among urologists across Catalonia, Spain. The survey was distributed through online platforms and the professional urology society. All statistical analyses were performed using Stata software, v20. RESULTS: 59 urologists completed the survey, revealing PLAR as the most commonly used technique (79.7%). Most urologist (70%) create the pneumoperitoneum using a controlled incision with direct access and 78.3% use the Airseal technology. The intraperitoneal approach is performed in >90% of cases. Endopelvic fascia preservation is not routinely performed. 34.5% of the survey not perform the dorsal vein complex suture. All preserves the bladder neck when oncologically safe. Nerve-vascular bundles bleeding control is performed using standard coagulation or suturing. 34% performed posterior reconstruction. Only use hemostatic devices when evident bleeding and 70% does not routinely left a drainage. Multivariable analysis showed that center volume had a significant independent association with dorsal venous complex suturing (OR 0.073, 95%CI 0.07-0.826), nerve-vascular bundles suturing hemostasis (OR 11.67, 95%CI 1.07-127.60) and endopelvic fascia preservation (OR 13.64, 95%CI 1.087-201.27), but there was no correlation with time the bladder catheter or days hospitalized. CONCLUSIONS: The study provides an overview of the state of PLAR in Catalonia, Spain, showing significant variability and reflecting a commitment to advancing surgical technology and patient care.
RESUMO
BACKGROUND: Levels of bone turnover markers (BTM) might be correlated with outcome in terms of skeletal-related events (SRE), disease progression, and death in patients with bladder cancer (BC) and renal cell carcinoma (RCC) with bone metastases (BM). We try to evaluate this possible correlation in patients who receive treatment with zoledronic acid (ZOL). METHODS: This observational, prospective, and multicenter study analysed BTM and clinical outcome in these patients. Serum levels of bone alkaline phosphatase (BALP), procollagen type I amino-terminal propeptide (PINP), and beta-isomer of carboxy-terminal telopeptide of type I collagen (ß-CTX) were analysed. RESULTS: Patients with RCC who died or progressed had higher baseline ß-CTX levels and those who experienced SRE during follow-up showed high baseline BALP levels. In BC, a poor rate of survival was related with high baseline ß-CTX and BALP levels, and new SRE with increased PINP levels. Cox univariate analysis showed that ß-CTX levels were associated with higher mortality and disease progression in RCC and higher mortality in BC. Bone alkaline phosphatase was associated with increased risk of premature SRE appearance in RCC and death in BC. CONCLUSION: Beta-isomer of carboxy-terminal telopeptide of type I collagen and BALP can be considered a complementary tool for prediction of clinical outcomes in patients with BC and RCC with BM treated with ZOL.

BACKGROUND: Owing to the limited validity of clinical data on the treatment of prostate cancer (PCa) and bone metastases, biochemical markers are a promising tool for predicting survival, disease progression and skeletal-related events (SREs) in these patients. The aim of this study was to evaluate the predictive capacity of biochemical markers of bone turnover for mortality risk, disease progression and SREs in patients with PCa and bone metastases undergoing treatment with zoledronic acid (ZA). METHODS: This was an observational, prospective and multicenter study in which ninety-eight patients were included. Patients were treated with ZA (4 mg every 4 weeks for 18 months). Data were collected at baseline and 3, 6, 9, 12, 15 and 18 months after the beginning of treatment. Serum levels of bone alkaline phosphtase (BALP), aminoterminal propeptide of procollagen type I (P1NP) and beta-isomer of carboxiterminal telopeptide of collagen I (ß-CTX) were analysed at all points in the study. Data on disease progression, SREs development and survival were recorded. RESULTS: Cox regression models with clinical data and bone markers showed that the levels of the three markers studied were predictive of survival time, with ß-CTX being especially powerful, in which a lack of normalisation in visit 1 (3 months after the beginning of treatment) showed a 6.3-times more risk for death than in normalised patients. Levels of these markers were also predictive for SREs, although in this case BALP and P1NP proved to be better predictors. We did not find any relationship between bone markers and disease progression. CONCLUSION: In patients with PCa and bone metastases treated with ZA, ß-CTX and P1NP can be considered suitable predictors for mortality risk, while BALP and P1NP are appropriate for SREs. The levels of these biomarkers 3 months after the beginning of treatment are especially important.

OBJECTIVE: To analyse changes in lipid profiles observed in patients receiving androgen deprivation therapy (ADT) and to evaluate differences between medical castration and maximal androgen blockade (MAB). MATERIAL AND METHODS: Serum levels of total cholesterol (TC), high-density lipoproteins (HDL), low-density lipoproteins (LDL) and triglycerides (TG) were prospectively evaluated in 33 patients with locally advanced or metastatic prostate cancer treated with ADT. The median age was 73.4 years. Serum lipids were measured at baseline and thereafter at 6 and 12 months. The modality of ADT was medical, with 3 months depot LHRH agonist, in 11 patients and MAB, by addition of 50 mg/day of bicalutamide, in 22 patients. RESULTS: TC increased from 210 to 227 mg/dl (p < 0.05), while LDL increased from 132 to 148 mg/dl (p < 0.05) at 6 months. There were no significant changes in HDL or TG levels. There were no significant differences in any of the analysed parameters after 12 months of ADT. The comparison between the group of patients treated with LHRH agonists alone and the group treated with MAB demonstrated no significant differences in any of the analysed parameters at 6 and 12 months (p > 0.05). CONCLUSIONS: Changes observed in TC and LDL after 6 months of ADT were transitory. No significant differences were observed according to the modality of ADT.

OBJECTIVES: The aim of this review is to present our experience in minimally invasive surgical procedures as treatment of hepatic and pulmonary hydatidosis in the last five years. MATERIAL AND METHODS: Retrospective review of patients with pulmonary and hepatic hydatid cysts treated in our hospital between 2008-2012 with minimally invasive surgery. RESULTS: We identified 4 cases, all of them Moroccan origin, the mean age was 6.7 years. Only one patient with hepatic cyst and three with hepatopulmonary cysts. All of them were treated with albendazole before surgery. Laparoscopy and/or thoracoscopy was performed and, in one case a transdiaphragmatic approach was used, as a way to reach a posterior hepatic injury unapproachable by laparoscopy. The technique used was the sterilization of the contents of the cyst with hypertonic saline solution, cyst opening and cystic membrane removal. We didn't do capitonage or pericystectomy. The resolution rate of residual cavities of the cysts was 100% and there was no recurrence or intraoperative complications. CONCLUSIONS: In children surgical treatment can be performed using endoscopic techniques with the same safety and efficacy as open surgery. Treatment with albendazole before surgery is helpful in preventing recurrences and as unique treatment in small lesions. Surgery must be as sparing as possible avoiding unnecessary liver or lung resections. Treatment of the residual cavity seems unnecessary. The thoracoscopic transdiaphragmatic approach should be considered as an alternative treatment, for those liver lesions in posterior segments, which are intractable with laparoscopy.

INTRODUCTION: In gastroschisis, premature birth may avoid the development of intestinal peel and favour the primary closure. We present the preliminary results obtained after following a multidisciplinary approach to gastroschisis. After prenatal ultrasound diagnosis, preterm caesarean delivery at 34-35 weeks of gestation is programmed. METHODS: Prospective design of a study, where we included all prenatal diagnosed gastrosquisis neonates, from July 2007 to January 2012. RESULTS: We followed 9 infants (3 male). Average weight at birth: 1,927 gr. (+/- 370). Primary closure was successfully accomplished in the first 3 hours of life all cases. We found two cases of slight peel. We found no associated intestinal malformations, except for one small bowel stenosis. No significant neonatal distress respiratory syndrome developed. Mean parenteral nutrition time was 13.9 days (+/- 3.8). 4 neonates developed central line associated infection. No surgical site infection developed. Enteral nutrition was started at day 8th (+/- 2.8). Enteral requirements were fulfilled at day 15th (+/- 3.6). Mean hospital stay was 31 days (+/- 10). Mean follow-up was 30 months. 4 cases developed a small (< 5 mm) umbilical hernia CONCLUSION: Programming premature cesarean section delivery at 34 weeks of gestation was beneficial to the neonates with gastroschisis, yet it avoided peel development, and rendered primary closure without serious difficulties possible. This diminishes hypoperistalsis time and allows rapid instauration of enteral feeding, so hospital stays may be shorter.

INTRODUCTION: Long term results of different surgical techniques in Hirschsprung's Disease (HD) are contradictory. There are still no long term large or multicentric reports about functional results of De la Torre technique. We have studied the mid term functional results of the patients operated on Duhamel (D) and De la Torre (dlT) pull-through procedures. PATIENTS AND METHODS: We collected data from medical records and telephone interviews of the HD patients operated in our unit in the last 16 years. RESULTS: 38 patients were found. Ages ranged from 1.5 to 21 years. Mean age was 7.7 years. Median follow up was 5.9 years. 33 (86.8%) had rectosigmoid disease and 5 (13.2%) had long segment disease. D procedure was performed in 17 (44.7%), Soave in 1 (2.6%), Duhamel-Lester-Martin in 4 (10.5%) and dlT pull-through in 16(42%). In the last visit record, 12 (31.6%), had constipation, and fecal leaks were noted in 11 (33.3%) of the 33 patients > or = 4 years old.. 10 patients (29.4% of the > or = 4 years old group) referred encopresis along the follow-up. Patients from the D group referred higher rates of constipation than those in the dlT group (53.3% vs 20% p=0.048). dlT patients referred more frequency of leaks (46,1% vs 13,3%, p=0,05) Children with very short resections (< or = 10 cm) were more prone to constipation than children with longer resections (66,6% vs 17.4% p=0.007), and less prone to present leaks (12.5% vs 47.3% p=0.08). Encopresis was similar in all groups. DISCUSSION: Both techniques show similar functional results in the mid term, although children in the D group were more prone to constipation and those in the dlT group presented more fecal leaks. All patients with EH need long follow-ups.

BACKGROUND AND OBJECTIVE: Prostate cancer (PC) is the malignant neoplasm with the highest incidence after lung cancer worldwide. The objective of this study is to review the literature on the methods that improve the efficacy of the current strategy for the early diagnosis of clinically significant PC (csPC), based on the performance of magnetic resonance imaging (RM) and targeted biopsies when suspicious lesions are detected, in addition to systematic biopsy. EVIDENCE ACQUISITION: A systematic literature review was performed in PubMed, Web of Science and Cochrane according to the PRISMA criteria (Preferred Reporting Items for Systematic Reviews and Meta-Analyses), using the search terms: multiparametric magnetic resonance imaging, biparametric magnetic resonance imaging, biomarkers in prostate cancer, prostate cancer y early diagnosis. A total of 297 references were identified and, using the PICO selection criteria, 21 publications were finally selected to synthesize the evidence. EVIDENCE SYNTHESIS: With the consolidation of MRI as the test of choice for the diagnosis of prostate cancer, the role of PSA density (PSAD) becomes relevant as a predictive tool included in prediction nomograms, without added cost. PSAD and diagnostic markers, combined with MRI, offer a high diagnostic power with an area under curve (AUC) above 0.7. Only the SHTLM3 model integrates markers in the creation of a nomogram. Prediction models also offer consistent efficacy with an AUC greater than 0.8 when associating MRI. CONCLUSIONS: The efficacy of MRI in clinically significant prostate cancer detection can be improved with different parameters in order to generate predictive models that support decision making.

INTRODUCTION: Urinary incontinence after radical prostatectomy (RP) is an adverse event with high impact on patient's quality of life. Nowadays there is no standardized method for urinary continence measurement. Posterior rhabdosphincter reconstruction (PRR) is a surgical step that can improve early urinary continence after RP. Our objective was to analyse different continence definitions and predictors of urinary continence recovery after robot-assisted RP (RARP). MATERIAL AND METHODS: We conducted a double-blind, randomised controlled trial (NCT03302169) including 152 consecutive patients with localized prostate cancer subjected to RARP. Patients were randomised to single urethrovesical anastomosis (control arm) or PRR before urethrovesical anastomosis (PRR arm). Urinary continence was measured with the EPIC-26 and ICIQ-SF validated questionnaires, and pad use (0-1 pads and no pads), at 7, 15, 30, 90, 180 and 365 days after catheter removal. Prognostic factors for early urinary continence recovery were analysed. RESULTS: 72 patients were included in the control arm and 80 in the PRR arm. Baseline characteristics were similar between arms, except body mass index, which was higher in PRR arm. "No pad" was the only definition assessing the benefit of PRR at 30 days, 33.8% in PRR arm and 18.1% in control arm, p = 0.022; and at 90 days, 58.8 and 43.1% respectively, p = 0.038. Questionnaires did not detect differences in terms of continence recovery. PRR was the only predictor for early continence recovery, p = 0.03. CONCLUSIONS: PRR increased early urinary continence recovery after RARP. Continence definition was critical to assess benefit. The only predictive factor for early continence recovery was PRR.

The management of intra-abdominal testis can be challenging, as evidenced by the multiple methods suggested for its assessment and treatment. In this paper, we report our long-term results for our 14-year surgical experience with laparoscopic management. Methods. Retrospective study of laparoscopic interventions performed at our department for nonpalpable testes between 1996 and 2009. In 174 procedures, we found 72 intra-abdominal testes (5 bilateral) and 25 direct orchiopexies (3 bilateral) were performed. One-stage Fowler-Stephens orchiopexies (FSO) were performed in 5 children. 40 boys underwent the two-stage FSO technique (2 bilateral) in those that reached the contralateral inguinal ring. The second stage was performed in 4 cases with a laparoscopic approach, the rest of them underwent an inguinal procedure exclusively. Mean age for the first intervention was 3.7 yrs, and the second stage was performed on average after 10.9 months. Of 42 undescended testes, 22 were on the right side and 20 on the left side. Median followup was 24 months. Results. Of 42 two-stage FSOs performed, 27 surgeries were very successful, with a testis size equivalent to the contralateral mate; 7 had good results, with a smaller testis (volume up to 50% of contralateral); and 7 resulted in atrophic testis. No complications were encountered during surgery. Conclusions. There is no doubt about the usefulness of laparoscopy for intra-abdominal testes with short spermatic vessels, and the two-stage Fowler-Stephens technique should be the procedure of choice given its high success rate.

OBJECTIVE: To review and update the latest scientific evidence gathered in recent years regarding prostate-specific antigen (PSA) for better implementation into routine clinical practice. EVIDENCE ACQUISITION: Analysis of the available evidence on the current role of PSA, based on the experience of an expert panel in the subject under analysis. EVIDENCE SYNTHESIS: Currently, PSA cannot be considered only as a guide for the presence or absence of prostate cancer. This determination can also help the urologist to decide on the most convenient treatment for a patient with benign prostatic hypertrophy (BPH) as a criterion for disease progression, and it can also suggest the suspicious existence of a prostatic tumor when there is PSA rise of>0.3 ng/ml over the level reached 6 months after having initiated treatment with 5-alpha-reductase inhibitor. However, the limits of this PSA rise with derivatives of alternative 5-alpha-reductase (5-ARI) inhibitors to dutasteride are controversial. Moreover, PSA is a key factor for the follow-up of patients with prostate adenocarcinoma at any stage who have received treatment (surgery, radiotherapy or focal therapies, hormone therapy), it acts as a guide to identify biochemical recurrence, to suspect the existence of local or distant recurrence, as well as to propose or discard adjuvant treatments. Finally, the role of PSA as a screening tool has been recently reinforced, demonstrating increased mortality rates or the existence of more aggressive cases of prostate cancer in those countries where the use of this tool has declined. CONCLUSIONS: We present new data about the current role of PSA in the management of patients treated for BPH and/or prostate cancer that should be implemented into routine clinical practice, with special emphasis on the relevant role of this biomarker in the screening and follow-up of prostate cancer, as well as in the progression of BPH in dutasteride treatment.

BACKGROUND: Repeat prostate biopsy (PBx) is recommended under persistent suspicion of prostate cancer (PCa) or in the face of the following findings: atypical small acinar proliferation (ASAP); extense (≥3 biopsy sites) high-grade prostatic intraepithelial neoplasia (HGPIN); or HGPIN with atypical glands; suspicious for adenocarcinoma (PIN-ATYP). Nowadays; multiparametric magnetic resonance imaging (mpMRI) and mpMRI targeted PBx (MRI-TBx) are recommended in repeat PBx. Our objective was to analyze the current value of ASAP; mHGPIN; PIN-ATYP and other histological findings to predict clinically significant PCa (csPCa) risk. METHODS: Retrospective analysis of 377 repeat PBxs. MRI-TBx was performed when Prostate Imaging-Reporting and Data System (PI-RADS) score >3 and 12-core transrectal ultrasound (TRUS) systematic PBx when ≤2. ASAP; HGPIN; mHGPIN; PIN-ATYP; and 8 other histological findings were prospectively reported in negative PBx. CsPCa was defined as ISUP group grade >2. RESULTS: Incidence of ASAP; multifocal HGPIN (mHGPIN) and PINATYP was 4.2%; 39.7% and 3.7% respectively; and csPCa rate was statistically similar among men with these histological findings. However; the rate of csPCa was 22.2% when proliferative inflammatory atrophy (PIA) was present; and 36.1% when it was not. PIA was the only histological finding which predicted lower risk of csPCa; with an OR of 0.54 (95%CI: 0.308-0.945; P = .031). In addition; PIA was an independent predictor of a model combining clinical variables and mpMRI which reached area under de ROC curve of 0.86 (95%CI: 0.83-0.90). CONCLUSION: PIA emerged as the only predictive histological finding of csPCa risk and can contribute to a predictive model. mHGPIN failed to predict csPCa risk. The low incidence of ASAP (4.2%) and PIN-ATYP (3.7%) prevented us from drawing conclusions.

BACKGROUND: Benign prostatic hyperplasia (BPH) represents the most frequent proliferative abnormality of the human prostate. In spite of the well-characterized architectural development of BPH, little is known about the cellular and molecular events that contribute to it. METHODS: We have developed an animal model to evaluate the follow-up of hormone-induced BPH and the analysis of the gene expression associated with BPH. Immunohistochemistry on human patient samples validated the BPH-related molecular alterations. RESULTS: Canine specific Affymetrix microarray analysis performed on sequential biopsies obtained from a beagle dog dynamic model characterized a number of genes altered during the onset of BPH. In addition to the genes involved in calcification, matrix remodeling, detoxification, cell movement, and mucosa protection (MGP, MMP2, TIMP2, ITIH3, GST, MT2A, SULT1A1, FKBP1B, MUC1, STRBP, TFF3), the up-regulation of TGFB3 and CLU indicated a complete adjustment of the transdifferentiation, senescence and apoptosis programs. The up-regulation of Clusterin was validated by RT-qPCR and immunohistochemistry, both in the dog dynamic model and in human samples, further confirming the suitability of the animal model for the study of the molecular alterations associated with BPH. CONCLUSIONS: Transcriptome analysis performed on a dynamic animal model that accurately mimicked the human clinic, allowed us to characterize a gene expression pattern associated with the onset of BPH.
